Unidentified insect: Beetle?

I’m posting this on Reddit ( /r/whatsthisbug). For you who once saw me post HERE rather regularly, I apologize for my long absence and offer this strikingly beautiful insect (a beetle?). I was seeing this orange-winged insect (probably a beetle) this spring, then suddenly it reappeared today in the Rio de Flag, Cheshire neighborhood, Flagstaff, Arizona.
